The present application provides a display device. The display device includes a display panel as shown in FIGS. 1 and 2.
According to one embodiment, as shown in FIGS. 1 and 2, the display panel 100 comprises a substrate 101 and a pixel layer 102 disposed on the substrate 101. The display panel 100 comprises a display region 01 and a non-display region 02. The display region 01 and the non-display region 02 are separated by a boundary line 03. The pixel layer 102 comprises a plurality of pixels 1021, wherein the pixels 1021 are divided by the boundary line 03, a portion of each pixel 1021 is disposed in the display region 01, the other portion of each pixel 1021 is disposed in the non-display region 02.
As shown in FIG. 2, each of the pixels 1021 comprises a plurality of sub-pixels 10211, and each of the sub-pixels 10211 has an area located in the display region 01, so that each pixel 1021 has corresponding area uniformity.
As shown in FIG. 3, the pixels 1021 comprise a plurality of first pixels 1022 and a plurality of second pixels 1023. The area uniformity of the first pixel is within a first predetermined range, and a shielding block 103 is disposed on the first pixel 1022. The area uniformity of the second pixel 1023 is outside the first predetermined range, and brightness of the second pixel 1023 is set according to an area of the second pixel 1023 in the display region 02.
The area uniformity of the pixel 1021 is [1−(S1−S2)/(S1+S2)], wherein S1 is an area of a first sub-pixel 10212 in the display region, S2 is an area of a second sub-pixel 10213 in the display region, the first sub-pixel 10212 of each pixel is the sub-pixel 10211 having a largest area in the display region 01, and the second sub-pixel 10213 of each pixel is the sub-pixel 10211 having a smallest area in the display region 01.
According to one embodiment of the present application, the first predetermined range is greater than 0.7 and is less than or equal to 1. This means that the areas of the sub-pixels 10211 in the first pixel 1022 in the display region 01 have relatively small differences. Typically, colors of the sub-pixels 10211 in the same first pixel 1022 are different. When the area uniformity is greater than 0.7 and less than or equal to 1, it indicates that the first pixel 1022 have similar proportions of the sub-pixels of different colors, so there are no large color shift problems, and properties of the shielding block 103 are uniform throughout, which facilitates the use of the shielding block 103 on the first pixel 1022 to improve the jagged images at an edge of a special-shaped display.
According to one embodiment of the present application, at least a portion of each of the shielding blocks 103 is disposed in the non-display region 02, the shielding block 103 shields the first pixel 1022 by using S/M as a minimum unit, wherein S is an area of the first pixel 1022, and M is within a second predetermined range.
According to one embodiment of the present application, the second predetermined range is between 4, 9, or 16. For example, when M is 9, the shielding block 103 shields the first pixel 1022 by using S/9 as the minimum unit. In other words, the minimum area of the shielding block 103 can be S/9. Accordingly, the area of the shielding block 103 can also be [(2*S)/9], [(3*S)/9], [(3*S)/9], and so on. It can be understood that precision of the shielding block 103 shielding the first pixel 1022 is S/9.
According to one embodiment of the present application, a section where the shielding block 103 on the boundary line 03 is a minimum unit has a target ratio, the target ratio is an area of the corresponding section in the display region 01 to an area of the corresponding section in the non-display region 02, and the target ratio of the section is less than 1.
The above configuration can slightly increase light transmittance of the display panel while shielding the non-display region 02.
According to one embodiment, each sub-pixel of the first pixel 1022 has an area that is not shielded by the shielding block 103, so that the first pixel 1022 has the corresponding area uniformity. The area uniformity of the first pixel 1022 is related to areas of a third sub-pixel and a fourth sub-pixel in the first pixel 1022 in the display region 01. The third sub-pixel is the sub-pixel of the corresponding first pixel 1022, which has a largest area unshielded by the shielding block 103. The fourth sub-pixel is the sub-pixel of the corresponding first pixel 1022, which has a smallest area unshielded by the shielding block 103. The area uniformity of the first pixel 1022 is [1−(S3−S4)/(S3+S4)], wherein S3 is an area of the third sub-pixel unshielded by the shielding block 103, and S4 is an area of the fourth sub-pixel unshielded by the shielding block 103. The area uniformity of the first pixel is greater than 0.9 and less than or equal to 1.
A range of the area uniformity of the first pixel 1022 is smaller than the area uniformity of the pixel, which means that areas of the sub-pixels 10211 in the first pixel 1022 unshielded by the shielding block 103 have small differences. By means of the above configuration of the shielding block 103, a color shift problem at the edge of the special-shaped display can be improved.
According to one embodiment of the present application, the third sub-pixel can be the first sub-pixel 10212, and the fourth sub-pixel can be the second sub-pixel 10213.
According to one embodiment of the present application, brightness of the second pixel 1023 can be increased according to an increase in the area of the second pixel 1023 in the display region 01. For example, for the second pixels 1023, a ratio of the brightness of each second pixel 1023 to the area of the second pixel 1023 in the display region 01 is equal. Further, the brightness of the second pixel 1023 can include brightness of each of the sub-pixels 10211, and the brightness of each of the sub-pixels 10211 can be set according to the area of the sub-pixel 10211 in the display region 01. For example, the brightness of each of the sub-pixels 10211 can be increased according to an increase in the area of the sub-pixel 10211 in the display region 01. A ratio of the brightness of each sub-pixel 10211 to an area of each sub-pixel in the display region 01 is equal. For more details, please refer to the following embodiments.
According to one embodiment of the present application, by controlling a magnitude of a driving voltage applied to each of the sub-pixels 10211 in the second pixel 1023, a magnitude of a grayscale value of each of the sub-pixels 10211 in the second pixel 1023 is controlled to provide different brightness levels.
According to one embodiment of the present application, by controlling an aperture size of a light filter arranged on the second pixel 1023, an amount of light transmitted through each of the sub-pixels 10211 in the second pixel 1023 is controlled to provide different brightness levels.
According to one embodiment of the present application, by controlling a length of each of the sub-pixels 10211 in the second pixel 1023, an amount of light emitted from or transmitted through each of the sub-pixels 10211 in the second pixel 1023 is controlled to provide different brightness levels.
It should be noted that, as shown in FIG. 4, the pixels 1021 comprises a main pixel 10214 and a subsidiary pixel 10215. The main pixel 10214 is disposed above the subsidiary pixel 10215, and a height of the main pixel 10214 is less than a height of the subsidiary pixel 10215. When the display panel 100 has low brightness, the main pixel 10214 and the sub-pixel 10215 in each of the pixels 1021 are respectively in an ON state and an OFF state. It can be understood that, for the pixel 1021 on the boundary line 03, if the boundary line is close to the main pixel 10214, burrs occur when the pixel 1021 uses the above-mentioned configuration for the second pixel 1023, so the pixel 1021 uses the above-mentioned configuration for the first pixel 1022.
The “low brightness” and “close” described in the present disclosure can be defined according to actual conditions.
In one embodiment of the present application, as shown in FIG. 5, the non-display region 02 in the display panel 100 is arranged around the display region 01, and the boundary line 03 used to separate the non-display region 02 and the display region 01 a closed curve. The boundary line 03 includes arcs 030 located at four corners of the display panel 100. The arc 030 can be a ¼ arc, a diagonal line 04 is used to divide the corresponding arc 030 into two equal parts, and the diagonal line 04 divides the boundary line 03 into a first sub-boundary line 031, a second sub-boundary line 032, a third sub-boundary line 033, and a fourth sub-boundary line 034, as shown in the drawing. In summary, the pixel 1021 on the first sub-boundary line 031 and the third sub-boundary line 033 can use the configuration for the second pixel 1023. The pixel 1021 on the second sub-boundary line 032 can use the configuration for the first pixel 1022. The pixel 1021 on the fourth sub-boundary line 034 can select the configuration for the first pixel 1022 or the second pixel 1023 according to a distance between the main pixel 10214 of the pixel 1021 and the fourth sub-boundary line 034.
The present application provides a manufacturing method of a display panel 100. As shown in FIGS. 2, 3, and 5, the display panel 100 comprises a display region 01 and a non-display region 02. The display region 01 and the non-display region 02 are separated by a boundary line 03. As shown in FIG. 6, the manufacturing method comprises:
S10: providing a substrate 101.
The substrate 101 can be an array substrate. The array substrate includes a plurality of gate lines parallel to each other and a plurality of data lines parallel to each other. The gate lines and the data lines are intersected to form a plurality of pixel regions. A thin film transistor is disposed in the pixel region.
S20: forming a plurality of pixels 1021 on the substrate 101, wherein the pixels 1021 are divided by the boundary line 03, a portion of each of the pixels 1021 is formed in the display region 01, the other portion of each of the pixels 1021 is formed in the non-display region 02, each of the pixels 1021 comprises a plurality of sub-pixels 10211, and each of the sub-pixels 10211 has an area located in the display region 01, so that each pixel 1021 has corresponding area uniformity.
The pixel 1021 is electrically connected to a source or a drain of the thin film transistor, the gate line controls an ON/OFF state of the corresponding thin film transistor, and the data line inputs a data signal to the corresponding thin film transistor to control the corresponding pixel 1021 to display images.
According to one embodiment of the present application, the area uniformity of the pixel 1021 is [1−(S1−S2)/(S1+S2)], wherein S1 is an area of a first sub-pixel 10212 in the display region, S2 is an area of a second sub-pixel 10213 in the display region, the first sub-pixel 10212 of each pixel 1021 is the sub-pixel having a largest area in the display region 01, and the second sub-pixel 10213 of each pixel 1021 is the sub-pixel having a smallest area in the display region 01.
In detail, an area of each of the first sub-pixels 10212 in the display region 01 can be obtained. An area S1 of the first sub-pixel 10212 in the display region and an area S2 of the second sub-pixel 10213 in the display region are obtained to calculate the area uniformity of the first sub-pixel 10212.
S30: determining whether the area uniformity of the pixel 1021 is within a first predetermined range.
In one embodiment of the present application, the first predetermined range is greater than 0.7 and less than or equal to 1. This means that the areas of the sub-pixels 10211 in the first pixel 1022 in the display region 01 have relatively small differences. Typically, colors of the sub-pixels 10211 in the same first pixel 1022 are different. When the area uniformity is greater than 0.7 and less than or equal to 1, it indicates that the first pixel 1022 have similar proportions of the sub-pixels of different colors.
S40: if it is determined that the area uniformity of the pixel 1021 is within the first predetermined range, defining the pixel 1021 as a first pixel 1022, and forming a shielding block 103 on the first pixel 1022.
It can be understood that, if the area uniformity of the pixel 1021 is within the first predetermined range, there are no large color shift problems, and properties of the shielding block 103 are uniform throughout, which facilitates the use of the shielding block 103 on the first pixel 1022 to improve the jagged images at an edge of a special-shaped display, as shown in FIG. 3.
According to one embodiment of the present application, at least a portion of each of the shielding blocks 103 is disposed in the non-display region 02, the shielding block 103 shields the first pixel 1022 by using S/M as a minimum unit, wherein S is an area of the first pixel 1022, and M is within a second predetermined range.
According to one embodiment of the present application, the second predetermined range is between 4, 9, or 16. For example, when M is 9, the shielding block 103 shields the first pixel 1022 by using S/9 as the minimum unit. In other words, the minimum area of the shielding block 103 can be S/9. Accordingly, the area of the shielding block 103 can also be [(2*S)/9], [(3*S)/9], [(3*S)/9], and so on. It can be understood that precision of the shielding block 103 shielding the first pixel 1022 is S/9.
According to one embodiment of the present application, a section where the shielding block 103 on the boundary line 03 is a minimum unit has a target ratio, the target ratio is an area of the corresponding section in the display region 01 to an area of the corresponding section in the non-display region 02, and the target ratio of the section is less than 1. The above configuration can slightly increase light transmittance of the display panel while shielding the non-display region 02.
According to one embodiment, each sub-pixel of the first pixel 1022 has an area that is not shielded by the shielding block 103, so that the first pixel 1022 has the corresponding area uniformity. The area uniformity of the first pixel 1022 is related to areas of a third sub-pixel and a fourth sub-pixel in the first pixel 1022 in the display region 01. The third sub-pixel is the sub-pixel of the corresponding first pixel 1022, which has a largest area unshielded by the shielding block 103. The fourth sub-pixel is the sub-pixel of the corresponding first pixel 1022, which has a smallest area unshielded by the shielding block 103. The area uniformity of the first pixel 1022 is [1−(S3−S4)/(S3+S4)], wherein S3 is an area of the third sub-pixel unshielded by the shielding block 103, and S4 is an area of the fourth sub-pixel unshielded by the shielding block 103. The area uniformity of the first pixel is greater than 0.9 and less than or equal to 1.
A range of the area uniformity of the first pixel 1022 is smaller than the area uniformity of the pixel, which means that areas of the sub-pixels 10211 in the first pixel 1022 unshielded by the shielding block 103 have small differences. By means of the above configuration of the shielding block 103, a color shift problem at the edge of the special-shaped display can be improved.
According to one embodiment of the present application, the third sub-pixel can be the first sub-pixel 10212, and the fourth sub-pixel can be the second sub-pixel 10213. For example, for each of the first pixels 1022, an area S2 of the second sub-pixel 10213 in the first pixel 1022 in the display region 01 can be used as a standard, so that an error between the S2 and an area of the second sub-pixel 1022 unshielded by the shielding block 103 is within a predetermined error range. At the same time, areas of the other sub-pixels of the first pixel 1022 unshielded by the shielding block 103 all satisfy the range of the area uniformity.
S50: if it is determined that the area uniformity of the pixel 1021 is outside the first predetermined range, defining the pixel 1021 as a second pixel 1023, and setting brightness of the second pixel 1023 according to an area of the second pixel 1023 in the display region 01.
According to one embodiment of the present application, brightness of the second pixel 1023 can be increased according to an increase in the area of the second pixel 1023 in the display region 01. For example, for the second pixels 1023, a ratio of the brightness of each second pixel 1023 to the area of the second pixel 1023 in the display region 01 is equal. Further, the brightness of the second pixel 1023 can include brightness of each of the sub-pixels 10211, and the brightness of each of the sub-pixels 10211 can be set according to the area of the sub-pixel 10211 in the display region 01. For example, the brightness of each of the sub-pixels 10211 can be increased according to an increase in the area of the sub-pixel 10211 in the display region 01. A ratio of the brightness of each sub-pixel 10211 to an area of each sub-pixel in the display region 01 is equal. For more details, please refer to the following embodiments.
According to one embodiment of the present application, by controlling a magnitude of a driving voltage applied to each of the sub-pixels 10211 in the second pixel 1023, a magnitude of a grayscale value of each of the sub-pixels 10211 in the second pixel 1023 is controlled to provide different brightness levels.
According to one embodiment of the present application, by controlling an aperture size of a light filter arranged on the second pixel 1023, an amount of light transmitted through each of the sub-pixels 10211 in the second pixel 1023 is controlled to provide different brightness levels.
According to one embodiment of the present application, by controlling a length of each of the sub-pixels 10211 in the second pixel 1023, an amount of light emitted from or transmitted through each of the sub-pixels 10211 in the second pixel 1023 is controlled to provide different brightness levels.
It should be noted that, as shown in FIG. 4, the pixels 1021 comprises a main pixel 10214 and a subsidiary pixel 10215. The main pixel 10214 is disposed above the subsidiary pixel 10215, and a height of the main pixel 10214 is less than a height of the subsidiary pixel 10215. When the display panel 100 has low brightness, the main pixel 10214 and the sub-pixel 10215 in each of the pixels 1021 are respectively in an ON state and an OFF state. It can be understood that, for the pixel 1021 on the boundary line 03, if the boundary line is close to the main pixel 10214, burrs occur when the pixel 1021 uses the above-mentioned configuration for the second pixel 1023, so the pixel 1021 uses the above-mentioned configuration for the first pixel 1022.
The “low brightness” and “close” described in the present disclosure can be defined according to actual conditions.
In one embodiment of the present application, as shown in FIG. 5, the non-display region 02 in the display panel 100 is arranged around the display region 01, and the boundary line 03 used to separate the non-display region 02 and the display region 01 a closed curve. The boundary line 03 includes arcs 030 located at four corners of the display panel 100. The arc 030 can be a ¼ arc, a diagonal line 04 is used to divide the corresponding arc 030 into two equal parts, and the diagonal line 04 divides the boundary line 03 into a first sub-boundary line 031, a second sub-boundary line 032, a third sub-boundary line 033, and a fourth sub-boundary line 034, as shown in the drawing. In summary, the pixel 1021 on the first sub-boundary line 031 and the third sub-boundary line 033 can use the configuration for the second pixel 1023. The pixel 1021 on the second sub-boundary line 032 can use the configuration for the first pixel 1022. The pixel 1021 on the fourth sub-boundary line 034 can select the configuration for the first pixel 1022 or the second pixel 1023 according to a distance between the main pixel 10214 of the pixel 1021 and the fourth sub-boundary line 034.
The present application provides a display panel, a manufacturing method thereof, and a display device. The display panel and the display device both comprises a display region and a non-display region separated by a boundary line. Each of pixels divided by the boundary line comprises a plurality of sub-pixels. According to areas of the sub-pixels in the display region, each pixel has corresponding area uniformity. According to whether the area uniformity is within a first predetermined range, a shielding block is arranged on the pixel, or brightness of the pixel is set according to an area of the pixel in the display region. This way, the present application solves a problem that jagged images appear at an edge of a special-shaped display and improves the display quality of the display panel.
